Definitions

  • the present invention relates to a travel plug adapter, which is also referred to herein briefly as a travel plug.
  • a travel plug adapter With the help of such an adapter, power plugs of a specific (domestic) standard can be plugged into the existing outlets at the place of travel.
  • the travel plug adapter requires a plug receptacle first standard and a power plug of another standard.
  • it is more accurate to travel plug adapters that allow plugging into sockets at least a first and a second standard.
  • mains plug of a first and a second standard can be used alternatively.
  • Travel plugs or travel plugs of this type are increasingly used in times of increasing global travel and business. There is therefore a need for compact, well portable travel plug adapters that are suitable for power outlets of several different standards.
  • the Chinese patent application CN 10187291 1 A discloses a travel plug adapter with a substantially round housing. Housing connectors are housed inside the housing, which can be selected and pushed out of the housing. In this way, at least three different types of power connectors can be used.
  • the selection of the desired power plug is done by the upper housing part is rotated relative to the lower housing part.
  • the upper housing part has a single outwardly projecting actuating slide. This actuating slide can be brought into engagement with different power plug elements. He will do so by twisting into a position placed above the out of the housing tenuzuschiebenden power plug.
  • This travel plug may be useful for many purposes. However, it would be desirable to provide a travel plug that is even easier to use. In particular, it appears advantageous if different controls are assigned to different plugs, and the plug can be transferred directly into the use position by operating the associated control element. Likewise, the return to a clearly recognizable and secured standby position should be well possible.
  • the German patent DE 10 201 1014920 B4 discloses another travel plug, which is referred to as a universal plug adapter.
  • this travel plug several plug pin sets are provided in an outer housing. Each pin set is connected to a keypad with which it can be moved from the outside.
  • the controls are guided through sliding slots in the housing.
  • the control units are additionally guided by a provided inside the outer housing locking plate.
  • This locking plate has a backdrop through which recesses, the controls can move.
  • the scenery provides an upper and a lower end position.
  • the locking plate is resiliently biased so that a control panel can be held firmly in the upper or in the lower end position.
  • the control panel and thus the corresponding pin set can be released from the end positions and moved up or down by an externally provided next to the controls additionally provided selector lever is actuated.
  • the selector lever By pressing this selector lever, the blocking plate is moved against the spring force.
  • the outer keypads are used both to transfer the pin sets from a first end position, a standby position, to a second end position, a use position, as well as to lock the pin sets in these positions.
  • the selector must be operated. This is a convenient one-handed operation in the way.
  • the controls occupy much space on the connector surface. This stands in the way of a free design-oriented design and the achievement of a compact design.
  • the object of the present invention is to provide an improved travel plug adapter which avoids the disadvantages of the prior art.
  • the travel adapter should be inexpensive and reliable to produce, easy to transport and operate and provide high electrical safety.
  • the travel plug adapter according to the invention has a housing which can have different shapes. For example, a cuboid shape is usually convenient for transport.
  • the mechanics of the travel plug adapter is, however, designed so that the housing form can be chosen largely freely. It is advantageous if the housing has at least one flat side, but the mechanism can also be adapted to curved housing surfaces.
  • the housing can be made in one piece or in several parts. It has proved to be expedient to carry out the housing in two parts, namely with a housing lower part and a housing upper part. Both can be releasably connected to each other, for example by mechanical means, expediently by a screw connection.
  • the housing should have at least one connector receptacle. This is expediently provided on the housing top.
  • the Plug receptacle Depending on the type of male power plug (hereafter short: plug), the Plug receptacle have different shapes. If, for example, a Schuko plug is to be received, then the plug receptacle will have a substantially cylindrical recess and, in addition, contact bushes for receiving the contact pins of the Schuko plug. Other types of plugs do not require a pit or pit. It may be expedient to provide a flat housing top, in which a plurality of contact sockets are provided. As a rule, at least two contact sockets should be provided, which form a pair of contact sockets for receiving a plug of a standard. It may be appropriate to provide multiple pairs of female contact to accommodate several plugs of different standard. If the plugs also have grounding and the plug receptacle to provide the possibility of grounding, it is usually necessary to provide per male plug and a third contact socket or a third contact.
  • the travel plug adapter should further comprise at least one plug of a first standard and a second plug of a second standard. (Such connectors are sometimes referred to as pin sets.)
  • the plug of the first standard may be, for example, an EU plug and the plug of the second standard to a US plug.
  • the plug can be bipolar, that is ungrounded, or even three-pole, so that a ground pole can be provided.
  • the present travel plug adapter is therefore suitable for use in more than one country. Expedient and usually also required if the first plug and the second plug are used alternatively.
  • the travel plug adapter may also include three or more plugs. Travel plug adapters with three or four plugs have proven to be very useful. At least one of the plugs, but generally all the plugs, can be brought from a standby position, in which the plug is located substantially in the housing, into a use position. In the use position the plug can be used whole or at least partially outside the housing. It is often possible for the plug to be completely moved back into the housing during the return to the ready position. It is expedient that the plug can at least be moved back into the housing so far that it is not in the way of other plugs.
  • the first connector is connected to an actuator for its transfer from the ready position to the use position.
  • the second plug is also connected to an actuator for its transfer from the ready position to the use position.
  • the travel plug adapter has at least a first actuating element and a second actuating element.
  • the actuators may conveniently be carried out in a button-like manner, so that they can easily be moved with one finger.
  • sliding slots can be provided in the housing. You can also connect sliding slots together, so that there is a guide link for the actuators. It is expedient, as a rule, to provide one slide slot per actuating element and to arrange these slide slots parallel to one another.
  • a selection slide can be provided, which can be brought at least in a first position and a second position.
  • This selection slide is alternatively in its first position, the first connector or in its second position the second connector for transfer to the use position free.
  • a blocking element as a blocking element can serve for example cams, which engage in the displacement track.
  • the housing of the travel plug adapter has sliding slots or similar recesses.
  • the actuators can run in these slide slots. It can also be additionally provided a sliding slot for a selection slide. Slide slots allow the movement of a slider while guiding. They thus represent an advantageous and inexpensive mechanical solution. Since usually several actuation slides are provided on the travel plug adapter, it is particularly advantageous if they can be guided in a simple manner in sliding slots. In the context of the present invention, the actuating slide only the movement of the plug, usually cause an up or down movement. The actuating slide must (unlike other conventional adapters) neither provide for the locking of the plug in the use position, nor cause that only one plug can be selected.
  • the actuators in the present invention are allowed to perform one function only, they can be easily and reliably guided in slide slots. If an actuating slide, for example, spring-loaded, the guide would be in a sliding slot in the Usually less user-friendly, the slider was prone to jamming, was "hakelig" and would have at least a higher resistance.
  • a locking element is associated with at least the first connector. With this, the plug can be locked in the ready position. By locking so the free displacement of the plug is reduced, in the standby position then the resistance to displacement in the use position is higher than in a middle position of the actuating element (a position between standby position and use position).
  • the locking element can assume an open position and a closed position, wherein the locking element can be transferred by the displacement of the first connector from the open position to the closed position.
  • the locking element can be transferred by the displacement of the first connector from the open position to the closed position.
  • the first plug is usually moved upwards, ie in its ready position.
  • the additional operation of a bolt or element for the transfer of the locking element in the closed position is not required.
  • the locking element is also transferred by the displacement of the first connector from the closed position to the open position.
  • the additional operation of a bolt or element for the transfer of the locking element in the open position is then not required. In order for the element to fulfill its function as a locking element, this transfer must, however, take place at least against a resistance and, in certain cases, can also be blocked, for example if another plug is already in the use position.
  • the locking can be done by a selection slide or otherwise, for example by a locking mechanism.
  • the locking element ensures the locking of the plug in the ready position. If the travel plug adapter has only a first plug, this is a mechanism provided that does not interact with other plugs. For example, a separate unlocking lever could be provided. It could also be provided in certain embodiments, an element for resilient bias of the locking element in the closed position. In any case, the locking element ensures that there is a clearly defined ready position. In known travel plugs without such locking elements, it is usually possible to move the actuator, such as an actuating slide, a little way towards the use position. This is also possible in most cases when mechanisms are provided which prevent the simultaneous transferring two plugs into the use position.
  • the locking element is designed as a completely separate from the actuator component.
  • the locking element can be performed as a movable lever. It is useful here a tiltable lever, in particular a lever which tilts about a single axis of rotation, preferably a rotational axis transverse to the direction of movement of the actuating element.
  • the lever may be resiliently biased towards its closed position, this may be provided alternatively or in addition to another closing mechanism.
  • a travel plug adapter in which each plug is assigned a support element and in which the locking element acts on the support element, so this possibly blocked and thus locks the plug in the standby position.
  • the support member may for example be designed as a support arm, which on the one hand carries the contact pins of the plug and on the other hand establishes a connection with actuator. It is expedient, in particular, if the support element has a recess and the locking element has a nose and the nose of the locking element can engage in the recess to hold the plug in the locked position. Particularly simple and convenient such a nose can form at the end of the lever.
  • the locking element can also be designed in other ways; The skilled worker is familiar with many solutions in this field.
  • a mechanical solution is selected, an electromechanical or friction or adhesion-based solution are also conceivable.
  • the locking element comprises a first unit which serves to ensure that the transfer from the ready position to the use position takes place against an increased resistance, preferably immediately after shifting from the standby position, but not on the whole way.
  • the locking element may also comprise a second element, which serves to block the transfer to the use position, for example because another plug is already in the use position.
  • Mechanical locking elements can be conveniently designed using two interlocking elements. For example, a projection may engage a recess, a cam may engage a hole or recess, a pin may engage a guide, etc.
  • a travel plug adapter in which a second plug of a second standard is also provided, to which an actuating element is likewise assigned, which serves for displacing the second plug between a standby position, in which the second plug is substantially inside the housing, and a use position, in which the second plug is usefully located outside the housing, is formed.
  • the second connector is associated with a second locking element, with which the second connector can be locked in the standby position and in turn can take an open position and a closed position.
  • the displacement paths of the first actuating element and the second actuating element define a displacement plane.
  • the locking elements are arranged behind this plane. This allows a particularly compact design of the travel plug and avoids that the mechanics of the actuators affect the mechanics of the locking elements. Moreover, it is perceived as visually pleasing if the mechanics of the locking elements is not visible through the bushings of the actuating elements through the connector housing, usually Gleitschlitze.
  • the locking elements rotate about a pivot point behind the displacement axis.
  • rotary axes can be provided there around which rocker arms rotate. Under the position "behind” the shift plane is a position toward the housing interior to understand.
  • the locking elements are also arranged above the actuating elements and thus generally above the sliding slots (or corresponding to the housing openings).
  • the locking element of the second plug can be transferred by moving the first plug from the open position to the closed position. This transfer can also consist in a mere fixation in the closed position.
  • the locking element then not only assumes the function of defining the safety-relevant readiness position of the plug exactly, but also ensures that the second plug is influenced by the position of the first plug.
  • the locking element can then take over the function, for example, has the twisting of the connector housing to select a connector or the function that may have in this context from selection slide.
  • the at least one locking element are connected to a control lever which allows or blocks the transfer of the at least one locking element (or possibly all locking elements) into the open position.
  • the control lever or finger can be designed as a separate element and connected to the locking element or be designed in one piece with the locking element.
  • a U-shaped lever has been proven, one end of the lever has an element or in particular a nose, which can interact with the plug or in particular a support element of the plug. The other end of the U-shaped lever can then serve as a control lever or finger. It is expedient if the control lever engages in a blocking unit which fixes the at least one locking element in the closed position.
  • the blocking unit can expediently at least one Have blocking slide, which can be moved substantially parallel to the axis of rotation of the at least one locking element. It is expedient if the at least one blocking slide (preferably all blocking slides) is arranged on a displacement track. It is also expedient if the at least one blocking slide is resiliently biased towards one end of the displacement track. All of these measures related to the blocking unit effect an effective interaction between the various plugs. In this case, as it were, the location information (use position or blocking position) on the position of the locking element and the control lever and then passed on the position of the blocking slide to further control lever and thereby locking elements.
  • the at least one blocking slide (or possibly all blocking slides) above the slide slots. It is also expedient to arrange the at least one blocking slide (or possibly all blocking slides) behind the sliding slots. This results in a favorable compact design and an optimized mode of operation with appealing exterior - as already outlined above for the position of the locking elements.
  • first blocking slide of a first length and a second blocking slide of a second length are provided.
  • the second length may be identical to the first length, but the second length may also be greater than the first length.
  • a larger second length makes it possible to make the distances of the various connectors unequal and even relatively free to choose, by adjusting the lengths of the blocking slide, but to achieve a reliable function of the blocking unit.
  • the plugs can be brought into the use position by means of the actuators.
  • Beneficial for the safe use of Travel plug adapters is that the plugs remain in the use position, even if they are inserted against pressure in a socket.
  • a locking or locking element In order to secure the whereabouts of plugs in the use position and to lock them there may be provided in the context of the present invention, a locking or locking element.
  • This latching element can lock at least one plug of the travel plug adapter, expediently, the latching element can also lock several or all plugs in the use position. It is useful if the locking element is connected to a release button, which is provided on the outside of the housing and to operate in a release direction.
  • release button allows the intuitive and safe release of the locking element when a plug is to be transferred from the use position back to the ready position. This construction appears safer and more reliable than those in which certain movements of the actuator or a selection slide or the plug itself lead to the release of the plug. So that the release button is not accidentally pressed, it can also be provided with warnings or in a warning color, for example in red, be designed.
  • the release button may be part of the housing, such as when a part of the housing can be pressed by suitable design. In general, it is expedient to provide a recess in the housing, and to provide the release button as independent of the housing part in this recess. Suitably, the release button opposite to the selector slide and / or the actuators are arranged.
  • the latching element is optionally resiliently biased against the release direction.
  • the resilient biasing of the locking element allows the reliable automatic engagement of plugs in a lock when the plug is in the use position. That's it mechanically advantageous when the springs act exactly opposite to the release direction.
  • An expedient embodiment of an (optional) latching element is one in which the latching element has at least one latching web and this latching web has a sliding surface and a latching projection. On the sliding surface, an element connected to a moving plug can slide along. This element can then engage the latching projection, so that the connector connected to the element is locked.
  • a travel plug adapter in which at least one plug has a sliding nose or is mechanically fixedly connected to such and the sliding nose runs on the sliding surface and can possibly assume a locking position on a latching projection.
  • the locking means comprises a plurality of locking webs, for example, two, three or four locking webs.
  • the number of locking bars can be just as large as the number of plugs. Appropriate and sufficient, it may also be, if the number of locking webs is less than the number of plugs.
  • both plugs are each connected to a sliding nose and both slide lugs run on the same latching web of the latching element. Since both sliding lugs run on the same locking bar, so both slide lugs on the same sliding surface and on the same locking projection on which both slide lugs can assume a locked position. Since in the travel plug adapter not two plugs should be transferred simultaneously to the use position, the sliding lugs take alternatively this locking position on the locking projection. However, by two Gleitnasen, for example, two sliding lugs adjacent plugs share a suitably sized locking ridge, the number of Detent webs are reduced and the travel plug adapters are built so compact.
